Question

what is
1/3x + 1/3(2x - 15)= 3 1/2

Answer 1

x = 13/2

Answer 2

(1/3)*(2*x-15)+(1/3)*x = 3*(1/2) // - 3*(1/2)

(1/3)*(2*x-15)+(1/3)*x-(3*(1/2)) = 0

(1/3)*(2*x-15)+(1/3)*x-3/2 = 0

1/3*(2*x-15)+x/3-3/2 = 0

(1/3*2*3*(2*x-15))/(2*3)+(2*x)/(2*3)+(-3*3)/(2*3) = 0

1/3*2*3*(2*x-15)+2*x-3*3 = 0

6*x-30-9 = 0

6*x-39 = 0

(6*x-39)/(2*3) = 0

(6*x-39)/(2*3) = 0 // * 2*3

6*x-39 = 0

6*x-39 = 0 // + 39

6*x = 39 // : 6

x = 39/6

x = 13/2
